The international manufacturers have directed
the thrust to higher precision, coupled with high productivity. Their
efforts are concentrated on improving the quality of the bearings to the
highest levels possible. Thus, the life of bearings would be improved, they
would carry higher loads and the noise levels would be reduced to the
Though bearing sizes and nomenclature have
been standardised, design modifications do take place continually in order
to improve the overall performance of the product. New products as such, may
not be a significant area of concentration. With the onslaught of excellent
quality volume production by the Japanese manufacturers, some bearing
manufacturers have moved towards bearings with special applications,
including ready assemblies that carry rolling bearings integrated into them.
Newer materials such as plastics and even
ceramics have been experimented with and developed for special applications.
Other manufacturers have re-organised to bring in economy of large volumes,
experimented and developed, such as use of plastics and even ceramics.
The pace and achievement of the above
mentioned goals in bearing manufacture can directly be linked to innovations
in machine tools, process technology and material properties. In machine
tools, the stress is constantly on improving the precision levels and
Automation at every stage is most common.
This is done within the machine and in
transfer from machine to machine into line manufacture, to achieve close
control on operations and monitor the pre-process corrections.
India V/s China Bearing Industry
In resent years, with the rapid development of
machinery industry, Chinese bearing industry is developing at a speed higher
than national economy. A lot of national key engineering projects, such as
delivery of west gas to the east, transmission of west electricity to the
east, transference of south water to the north, Three Gorges reservoir on
the Changjiang River, Beijing Olympic Games in 2008, and Shanghai World
Exhibition in 2010, will need great amount of machinery as well as great
amount of bearings.
This situation will provide large market space
for bearing industry development. It is estimated that in a few years,
bearing market will grow at a speed of over 10%.
In 2005, market capacity of Chinese bearing
industry was nearly 5 billion sets.
Major demand for bearings in China in near
According to analysis, major demand for bearing products in China in near
future will be in four categories.
First category is bearings for automobile and
motorcycle. These bearings have large demand and high additional value. This
category includes hub bearing, separating bearing in clutch,
shaft-connecting bearing in water pump, compressor bearing in air
conditioner, bearing in gear box, bearing in engine, and so on.
Second category is bearings with high
technology and high reliability, such as bearing in locomotive, passenger
train and freight train, bearing in steel rolling mill, and bearing in
Third category is sealed bearings of high
precision and low noise, such as spindle bearing in machine tool, bearing in
electric motor, bearing in soft and hard drive of computer, and so on.
Fourth category is bearings for agricultural
machinery and agricultural vehicle.
China aims of world largest bearing
Since bearing industry is the industry of
labor intensity and technology intensity. With labor cost increasing
continuously, many foreign bearing companies are entering China. Ten largest
bearing companies in the world have established factories of joint-venture
or of their own investment in China. Recently, new projects and new
factories are being constructed with increasing scale. Famous bearing
companies, such as NSK and Timken, are supplementing investment to set up
factories in China.
Comparative Advantage of machinery industry
Consider the Luoyangn province which
is like Jaipur in India where the first bearing enterprise stated in China
today has a strong foundation of machinery industry, as there are many
large machinery factories in the city. China First Tractor Group, Luoyang
Bearing Group, Luoyang Copper Processing Group, Zhongxin Heavy Machinery
Company and Luoyang North Ek Chor Motorcycle Company are all well-known
enterprises in China and in the world.
There are 500 thousand workers and 120
thousand technicians in the city. There are more than 300 scientific and
technical research institutes, in which 14 are national research institutes,
6 are national technology centers and 6 are national examination centers.
